Sample ME8594 Important 8 Mark Questions Dynamics Of Machines:
For reciprocating engine, derive the expression for
(i) Velocity and acceleration of thepiston (7)
(ii)Angular velocity and angular acceleration of the connectingrod
In a reciprocating engine mechanism, if the crank and connecting rod are 300mm and 1m long respectively and the crank rotates at a constant speed of 200 r.p.m. Determineanalytically,
1. The crank angle at which the maximum velocity occursand (7)
2. Maximum velocity of piston.3. Derive the relevantequations (6)
Derive equation of forces on the reciprocating parts of an engine neglecting the weight of the connecting rod. (13) ME8594 Important 8 Mark Questions Dynamics Of Machines
(i) A vertical double-acting steam engine develops 75 KW at 250 r.p.m. The maximum fluctuation of energy is 30% of the work done per cycle. The maximum and minimum speeds are not to vary more than 1% on either side of the mean speed. Find the mass of the flywheel required if the radius of gyration is 0.6metres.(6)
(ii)The radius of gyration of a fly wheel is 1meter and fluctuation of speed is not to exceed 1% of the mean speed of the flywheel. If the mass of the flywheel is 3340kg and the steam develops 150 KW at 135 r.p.m., then find, 1. Maximum fluctuation of energy 2. Coefficient of fluctuationofenergy.(7) ME8594 Important 8 Mark Questions Dynamics Of Machines
The length of crank and connecting rod of a horizontal reciprocating engine are 100 mm and 500 mm respectively. The crank is rotating at 400 r.p.m. When the crank has turned 30° from the IDC, find analytically 1.Velocity of piston 2.Acceleration of piston 3. Angular velocity of connecting rod 4. Angular acceleration of connectingrod.
